Hardware (computer).
Magnetic tape drives use magnetic tape similar to the tape used in VCR cassettes. Tape drives have a very slow read/write time, but have a very high capacity; in fact,their capacity is second only to hard disk drives. Tape drives are mainly used to back up data. Compact disc drives store information on pits burned into the surface of a disc of reflective material ( see CD-ROM). CD-ROMs can store up to 737 megabytes (MB) of data. A Compact Disc-Recordable (CD-R) or Compact Disc-ReWritable (CD-RW)...

Hardware - ciencia y tecnologia.
Algunos dispositivos se utilizan para varios fines diferentes. Por ejemplo, los disquetes también pueden emplearse como dispositivos de entrada si contienen informaciónque el usuario informático desea utilizar y procesar. También se pueden utilizar como dispositivos de salida si el usuario quiere almacenar en ellos los resultados de sucomputadora. 5 CONEXIONES DEL HARDWARE Para funcionar, el hardware necesita unas conexiones materiales que permitan a los componentes comunicarse entre sí e in...

Mountain Climbing.
teeth on one side, and a straight, flat, metal blade called an adze on the other. Ice axes have many uses. One of the most common is to help the climber stay balanced on steep slopes. The climber swings the axe with a short, quick movement to lodge the pick in snow or ice, creating a secure anchor. If a climber should slip and beginsliding down a snowfield, a self-arrest can be performed by turning face down on the snow and burying the pick in the snow surface. The climber’s weight over the...

Computer.
which can activate computer commands in conjunction with voice recognition software. “Tablet” computers are being developed that will allow users to interact with theirscreens using a penlike device. E The Central Processing Unit Information from an input device or from the computer’s memory is communicated via the bus to the central processing unit (CPU), which is the part of the computerthat translates commands and runs programs. The CPU is a microprocessor chip—that is, a single piece of sil...

[TD Sociologie] Le phénomène religieux et le phénomène "geek", analyse comparée
• Les symboles A) Technologies et informatique L'univers geek se matérialise sur un grand nombre de supports. Nous différencions les supports physiques ou matériels des supports immatériels. Avec l'Internet de plus en plus pregnant il est difficile de séparer absolument ces deux grands ensembles. En effet, si l'on prend le seul cas d'Internet il est impossible de le classer ou bien dans les supports puremen...

El ordenador - (exposé gratuit en espagnol).
FUNCIONAMIENTO DEL ORDENADOR Los primeros ordenadores solo servían para realizar cálculos matemáticos, pero en la actualidad se usan con fines muy variados. Encualquier caso, el esquema de funcionamiento de un ordenador siempre es el mismo: 1. Primero hay que introducir datos en el ordenador: se puede hacer a mano, mediante el teclado, o introduciéndolos desde algún soporte, como un disquete o un CD-ROM. 2. A continuación, el ordenador procesa los datos. 3. Por último, el ordenador nos propo...

Computer Science.
theoretical research is called algorithmic complexity. Computer scientists in this field seek to develop techniques for determining the inherent efficiency of algorithmswith respect to one another. Another area of theoretical research called computability theory seeks to identify the inherent limits of computation. Software engineers use programming languages to communicate algorithms to a computer. Natural languages such as English are ambiguous—meaning that theirgrammatical structure and vocab...

Electronic Games.
arcade game of all time. With Pizza Time Theaters legitimizing the idea of arcades and hits such as Ms. Pac-Man , Asteroids , Donkey Kong , Tempest , Frogger , and Defender bringing new excitement to gaming, the coin-operated video game business boomed. In 1981 Americans spent 75,000 person-years and $5 billion playing video games at anestimated 4,300 arcades in the United States. Many popular arcade games also were translated for use on the Atari 2600 and its chief rivals in the homemarket—M...
